Assembly

 Before any work on the machine itself (e. g. mainte-

nance, tool change, etc.) as well as during transport

and storage, remove the battery from the power tool.

There is danger of injury when unintentionally actuating

the On/Off switch.

Battery Charging

 Use only the battery chargers listed on the accessories

page. Only these battery chargers are matched to the lith-

ium ion battery of your power tool.

Note: The battery is supplied partially charged. To ensure full

capacity of the battery, completely charge the battery in the

battery charger before using your power tool for the first time.

The lithium ion battery can be charged at any time without re-

ducing its service life. Interrupting the charging procedure

does not damage the battery.

The Lithium-Ion battery is protected against deep discharging

by the “Electronic Cell Protection (ECP)”. When the battery is

empty, the machine is switched off by means of a protective

circuit: The inserted tool no longer rotates.

 Do not continue to press the On/Off switch after the

machine has been automatically switched off. The bat-

tery can be damaged.

The battery is equipped with a NTC temperature control

which allows charging only within a temperature range of be-

tween 0 °C and 45 °C. A long battery service life is achieved

in this manner.

Observe the notes for disposal.

Removing the battery

The battery 1 is equipped with two locking levels that should

prevent the battery from falling out when pushing the battery

unlocking button 10 unintentionally. As long as the battery is

inserted in the power tool, it is held in position by means of a

spring.

To remove the battery 1, press the unlocking button 10 and

pull out the battery toward the front. Do not exert any force.

Battery Charge-control Indication (see figure A)

The three green LEDs of the battery charge-control indicator

16 indicate the charge condition of the battery 1. For safety

reasons, it is only possible to check the status of the charge

condition when the machine is at a standstill.

Press button 15 to indicate the charge condition. This is also

possible when the battery 1 is removed.

When no LED lights up after pushing button 15, then the bat-

tery is defective and must be replaced.

Inserting/Replacing the Band-saw Blade

 Always wear protective gloves when mounting the

band-saw blade. Danger of injury when touching the

band-saw blade.

loose and cause injury.

Auxiliary Handle (see figure F)

 Operate your machine only with the auxiliary handle 9.

Screw the auxiliary handle into the corresponding threaded

hole 18 in the housing.

Dust/Chip Extraction

 Dusts from materials such as lead-containing coatings,

some wood types, minerals and metal can be harmful to

one’s health. Touching or breathing-in the dusts can cause

allergic reactions and/or lead to respiratory infections of

the user or bystanders.

Certain dusts, such as oak or beech dust, are considered

as carcinogenic, especially in connection with wood-treat-

ment additives (chromate, wood preservative). Materials

containing asbestos may only be worked by specialists.

– Provide for good ventilation of the working place.

– It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the

materials to be worked.

 Prevent dust accumulation at the workplace. Dusts can

easily ignite.
